IMPROVEMENT IN WATCHMENS TivlE-@ETCTERS.

Specification forming part of Letters Patent No. 194,006. dated August 7, 1877 application led November 21, 1876.

To all whom it may concern:

Beit known that I, GEORGE W. SHINGLE- TON, of Indianapolis, county of Marion, State of Indiana, have invented a new and useful Clock-Register, of which the following is a description, reference being had to the accompanying drawings.

The object of my invention is to construct a clock with a register addition, and to provide the register part with proper punchknobs, so thatanurnber of Workmen can register the time at which they go to work, or a person designated can register the time for them 5 and my invention consists of extending the shaft of a clock, to which the hour-hand is attached, backward beyond the clock-back, and attaching thereto a paper dial properly spaced, and lettered or gured, which shall revolve with the hour-hand; and also of constructin g a disk attached to the rear door of the clock with proper punch-knobs, which should be lettered or numbered the same as the workmen, which, when operated or pushed in, shall punch the paper dial and designate the time the workmen went to work.

Figure l represents the back of an ordinary clock, showing the arrangement of the paper dial on the extended part of the hour-hand shaft. Fig. 2 represents the paper dial. Fig. 3 is a sectional view of a clock, showing the arrangement of my improved register. Fig. 4 represents the rear door of the clock in which the punch-knobs are operated. Fig. 5 is an enlarged view.

A represents the outer case of an ordinary clock provided with the front F, to which is attached the dial G in the ordinary manner.

The clock-works operate in the space K, be-

tween the dial G and back L, but are not shown.

The hour-hand H is secured to the shaft J, and operates in the usual manner; but the shaft J extends through the back L, and is provided with a feather, t. On this shaft fits nicely a sleeve, E, having a groove, m, to receive the feather t, and a flange or disk, O, for supporting a register-disk, B, which is arranged with its face next to the back L of the clock. y

The register-disk is printed in the manner shown in Fig. 2, having twelve lines, v7 7 7,

' ber of minutes that he is late,and so on. Each dto., radiating from a common center. Thes radial lines indicate, each one, one hour apart and between these lines 7 7 7, dto., there ar other radial lines which subdivide the spac into spaces equal to ten minutes each. Thu the spaces all indicate ten minutes7 time be tween each radial line. lThe radial lilies ar4 also crossed by circles 1 2 3 4 5 6, Sto., and i at the crossing of each circle-line with a radia line, if a punch-key, S r1 r2, was pushed in the dial B would be perforated with a hole as g or g in Fig. 1, which will be hereinaftei described.

The rear clock-door T is hinged at V to the case A, and is designed to be further secured by a lock to prevent its being opened by any person other than the one who has charge thereof. On the door T the disk O is secure( by proper studs P P.' These studs are hollow and in the hollow part the shank r1 of the punch-knobs S operate. Between the end: ofthe shanks lr1 and the end of the socket ir the studs P a coil-spring, s, is used to forel the knobs S out after having been pressed in Into the ends of ythe shanks r1 are insertct the punches r2, which extend through a per foration in the disk O far enough to almost touch the register-disk B when the door T il closed, as shown in Fig. 3.

The operation of my improved register is as follows The disk B being secured to theshaf J, and heldin position by thepinsff, (shown it Fig. 1,) the disk B revolves with the hour-haut H. lfworkmanNo-1comes in at seven oclocll and presses the knob No. l in. the punch r2 or the end perforates the register-disk B at the register-mark 7 oclock, as shown at g in Fig l, and it' workman No. comes in at the same time, his register-mark will be the same, only at g, Fig. 1, and if either is late,the perforated hole opposite hisnumber will register the num workman registers his own time for record and there can be no mistake.

lt will be seen that by the arrangement de scribed a single disk is made to serve the pur pose of a number of disks and separate cloch movements, as heretofore 5 that the sleeve E carrying the register-disk B, may be readily applied and withdrawn withoutdanger of mal adjustment, and that the said sleeve and the disk O, with its studs and pnnehes, may be n testimony whereof I have signed my readily applied to ordinary clocks Without any name to this specification in the presence of' other alteration than to extend the hour-shaft two subscribing witnesses.
